Animal structure and life cycle

1. Mrs. Krajewski Animal structure and life cycle

2. Characteristics: • 1. made of cells • 2. They reproduce • 3. They move • 4. They eat food • 5. They grow and change Characteristics of animals

3. Vertebrates invertebrates • All animals that have backbones. • Fish, amphibians, retiles, birds, and mammals • All animals that do not have a backbone. • Arthropods- (insects, crabs, spiders) • Text p. 22-23 • Answer checkpoint question 1 on p. 23 Vertebrates vs.Invertebrates

5. Warm blooded cold blooded • The body of a Warm Blooded animal does not change much. • The body of a Cold Blooded animal changes depending on their surroundings. Warm blooded vs. cold blooded

6. Animals are classified into different types of groups.: To study the many forms of animal life in a systematic way, scientists have divided the animal kingdom into groups. These groups are largely based upon the structure of the animal's body. Information is from: http://kids.britannica.com/comptons/article-196401/animal • Insects • Amphibians • Mammals • Reptiles • Fish • Birds Open up to textbook p. 18 Animal classifications

7. Fish are usually covered in scales. They live only in water. Fish breathe mostly by using their gills. Fish are cold blooded and most lay eggs. • There are three classes of fish: • the primitive jawless fishes, or Agnatha • the cartilaginous (shark like) fishes, or Chondrichthyes • the bony fishes, or Osteicht http://answers.encyclopedia.com/question/three-classes-fish-86809.htmlhyes. FISH

8. Amphibians are covered with a smooth skin • They can live on both land and in the water. • They breathe by using their gills or with lungs, sometimes even both! • They are cold blooded • They hatch from eggs Amphibians

9. Reptiles are covered in scales • Most reptiles live on land • Some can live in water • They use their lungs to breathe • They are cold blooded • They usually lay eggs Reptiles

10. Birds are covered with feathers. • They usually live on land, but some spend a great deal of time on water • Birds breathe using lungs • They are warm blooded • They lay eggs BIRDS

11. All mammals have hair or fur • Most live on land, but a few live in water • They use lungs to breathe • Mammals are warm blooded, they control their body temperature • Most mammals have live births mammals

12. Draw this chart in your copybook and list whether each classification is cold blooded or warm blooded: FISH, AMPHIBIANS, REPTILES, BIRDS, MAMMALS Apply to learning

13. Match the picture to the classification Bird Amphibian FISH Reptile Mammal

14. Create a graph that compares the size of animals to the number of young they bear. Create a graph

15. Life cycles of animals Animals have a variety of life cycles. Each life cycle depends on the species and can vary greatly. Let’s read pages 20 and 21 together!

16. Let’s see some examples!

19. Research: what is the average life span of each animal?
